Endogenous Transportation Technology in a Cournot Differential Game with Intraindustry Trade

  • L. Colombo
  • L. Lambertini
  • A. Mantovani

We investigate a dynamic Cournot duopoly with intraindustry trade, where firms invest in R&D to reduce the level of iceberg transportation costs. We adopt both open-loop and closed-loop equilibrium concepts, showing that a unique (saddle point) steady state exists in both cases. In the open-loop model, optimal investments and the resulting efficiency of transportation technology are independent of the relative size of the two countries. On the contrary, in the closed-loop case firms' R&D incentives are driven by the relative size of the two countries. Policy implications are also evaluated.
